The collections of the Tiled Kiosk Museum consist of about 2000 artifacts belonging to the Seljuk and Ottoman eras, dating from the 11th-20th centuries. These artifacts include those that existed when the museum was incorporated into the İstanbul Archaeological Museums due to its closeness and those acquired through excavations, purchases, donations and confiscations.
